That depends on your config file. Natively you can send up to 65535 bytes in one TCP transmission. As far as I remember, its the TCP_WND #define, controlling this. If you need more bigger massages, you need to replace a lot of u16 by u32. There is also an oversize patch somewhere, doing this correctly.
